Title: Arrangement for controlling air-fuel in internal combustion engine
Inventor: TOYODA KATSUHIKO
IPC: F02D41/00
Filed: 1998-12-01
Abstract: The arrangement has a controller for the quantity of flushing gas fed into an engine induction system and performs a learning control process for the air/fuel ratio in which the individual differences of components associated with the engine are taken into account. A control device sets air/fuel ratio learning process numbers in several learning zones, where the numbers determine whether the ratio learning process will be conducted on the basis of engine revolution rate and load. The control device performs a forced learning control process with the flushing gas quantity as a fixed value in the event that the ratio learning process is not performed for a given number of times in all learning zones in which the process numbers are set. An Independent claim is included for a method of controlling the air/fuel ratio in an internal combustion engine.

Title: Dynamic random access memory (DRAM) cell capacitor fabricating method
Inventor: PARK BYUNG-JUN
IPC: H01L27/108
Filed: 1999-02-26
Abstract: The method involves providing a semiconductor substrate (10) with a pair of source/drain regions aligned with the lateral edges of a gate electrode. A pair of storage contact pads is formed to the source/drain regions. A first insulating layer is formed over the substrate. A conductive layer pattern (24a) is formed over the first insulating layer (18,20), overlapping one of the storage contact pads (16) and extending in a lateral direction of the one of the pads. A second insulating layer (28) and a first material layer (30) are sequentially formed over the first insulating layer including the conductive layer pattern. The first material layer has etch selectivity with respect to the second insulating layer. The first material layer, the second insulating layer, and the conductive layer pattern are sequentially etched using a first photolithography. A first opening (32) is formed to the first insulating layer over the one storage contact pad and penetrates one end of the conductive pattern. Conductive sidewall spacers (34) formed in the first opening are used with the first material layer as a mask. The first insulating layer is etched down to the one storage contact pad. A second opening (36) is also formed. A conductive material deposited in both openings and over the first material layer is planarized down to the second insulating layer to form a first conductive pole (38). The second insulating layer is etched until the first insulating layer and the other end of the conductive layer pattern is exposed using a second photolithography. A third opening, formed spaced apart from the first opening, is filled with the same material as the first conductive pole to form a second conductive pole (44) which is connected to the first through the conductive layer pattern. The poles and the conductive layer pattern constitute a storage electrode of the DRAM capacitor. An Independent claim is included for a DRAM cell capacitor.
